Recent studies on adult patients' perceptions of their hospital care have shown that improvements are needed in pain management (Jha, Orav, Zheng, and Epstein). The use of regional anesthetic techniques to block specific peripheral nerves in adult patients has increased in recent decades as an alternative to general anesthesia or to decrease opioid use during and after surgery. Decreased postoperative complications have been observed, with fewer ambulatory patients requiring prolonged recovery room stays and/or costly unplanned hospital admissions (Chan, Peng, Kaszas, Middleton, Muni, Anastakis, and Graham).
